[Mandibular fibrous dysplasia: a monostotic form].
BACKGROUND
The onset of one or several diastema in adults with no link of etiology to tooth loss or to a periodontal problem can be the first evocative sign of an acromegaly or a benign or malignant tumoral process.


METHODS
A 40-year-old patient consulted for an implant to solve an esthetic problem caused by a diastema. The complementary exams revealed an osteolytic lesion marked by condensing areas. The biopsy proved the diagnosis of fibrous dysplasia.


CONCLUSIONS
Etiologies of fibrous dysplasia are varied. They can be related to a congenital defect of osteo mesenchyma development or be the consequence of trauma, reaction to infection, or an endocrine or metabolic disorder.
